Frequently Asked Questions (FAQ)
Q: Why is this transformer specifically designed for airport applications?
A: Leilang Electric's 1600KVA airport transformer features enhanced reliability, on-load tap changing for uninterrupted power, and 200KV BIL protection—all essential for supporting 24/7 critical airport operations including navigation systems, runway lighting, and terminal power.
Q: What is the benefit of the on-load tap changer (OLTC) in airport applications?
A: The OLTC allows voltage regulation without power interruption, ensuring stable voltage output even during peak load periods. This prevents equipment damage and downtime for sensitive aviation systems that require constant, reliable power.
Q: What does the 200KV BIL rating mean for airport power systems?
A: A 200KV Basic Impulse Level rating means the transformer can withstand high-voltage transient surges from lightning strikes and switching operations. This is critical for airports, which are often located in open areas with high lightning exposure.
Q: How much energy can I save with the S11 ultra-low loss design?
A: The S11 series reduces no-load losses by 30% and no-load current by 70-85% compared to S9 series transformers. For a 1600KVA transformer operating 24/7, this translates to over 8,700 kWh of annual energy savings, significantly lowering operational costs.
Q: How does the fully sealed tank design extend transformer life?
A: The fully sealed structure prevents transformer oil from contacting air, eliminating oxidation and moisture absorption. This reduces oil degradation, extends insulation life, and minimizes maintenance requirements, resulting in a longer service life and lower total cost of ownership.
